About the Dux Ecosmart 285L Heat Pump

The Dux Ecosmart 285L Heat Pump is part of Dux’s third generation Ecosmart heat pump range. It is designed to absorb heat from the surrounding air and use reverse cycle technology to heat stored water more efficiently than a standard electric water heater.

The 285L model is designed for larger families and homes with higher hot water demand. It is commonly suited to households replacing an electric water heater on a continuous tariff or time-of-use tariff and wanting to reduce water heating energy use.

Dux states the Ecosmart 285L model can use up to 71.6% less energy than a standard electric water heater under stated modelling conditions. Actual savings can vary depending on the water heater being replaced, installation location, household hot water use and energy tariff.

The 285L model is also designed with the same tank diameter as selected Dux Proflo 250L and 315L electric water heaters, making it a practical heat pump upgrade option for many replacement situations where the existing footprint is suitable.

Energy Efficient Heat Pump Design

The Dux Ecosmart 285L Heat Pump is designed to use heat from the surrounding air to heat water more efficiently than a standard electric storage water heater.

Heat pump technology works by absorbing free ambient heat energy from the air and transferring it into the stored water. This can help reduce energy use and running costs when the system is correctly selected, installed and used under suitable tariff and household conditions.

The 285L model is listed with a COP of 4.63, meaning it can produce more heat output than the electrical energy it consumes under the stated test conditions.

Smart Wi-Fi Control

The Dux Ecosmart 285L includes a Wi-Fi enabled touchscreen controller and can be controlled through the Smart Life app when connected to the internet.

The app and controller allow users to view system status, check stored water temperature, select operating modes, use boost functions, schedule heating times and help align operation with time-of-use tariffs or excess solar PV generation where suitable.

Smart control features may include:

• Eco mode for energy-conscious operation

• Boost mode for higher recovery demand

• Holiday mode for periods when hot water is not required

• Single shot boost for faster recovery

• Timer scheduling

• Stored water temperature visibility

• Remote status monitoring through the app

• Notifications and error visibility

• Settings retained after power interruption

Australian Designed and Manufactured

The Dux Ecosmart heat pump range is proudly designed and manufactured in Australia for Australian homes and conditions.

The 285L model uses R290 compressor technology, electronic expansion control valves, anti-corrosive coatings, UV stable polymers and fire retardant materials. Dux also lists the Ecosmart range as going through an 18-point quality test before leaving the factory.

This makes the Ecosmart 285L a strong option for customers wanting an Australian made heat pump from an established hot water brand.

Government Incentives and STCs

The Dux Ecosmart 285L Heat Pump may be eligible for government incentives where requirements are met.

Dux lists the Ecosmart range as eligible for incentives including Small-Scale Technology Certificates and other state-based programs where applicable. Eligibility, rebate value and discount structure can vary depending on installation year, location, product model, installer requirements and program rules.

Any rebate or incentive should be confirmed before ordering or installation.

Tempering Valve and Element Information

*Element size information:
All electric hot water units are supplied as standard with a 3.6kW element unless otherwise stated on the product page, invoice, or order confirmation.

If a different element configuration is requested, such as 1.8kW or 2.4kW, the hot water unit may still arrive with the standard 3.6kW element fitted from the manufacturer. The requested 1.8kW or 2.4kW element will be supplied separately with the order for installation by a suitably licensed electrical contractor or licensed electrical licence holder.

Any element changeover, electrical connection, disconnection, wiring, testing, or modification must be carried out by a licensed electrical contractor or licensed electrical licence holder. Elements must not be changed, connected, modified, or tested by an unlicensed person.

Alternative elements supplied for non-standard configurations may be generic replacement elements and may not be the same brand as the hot water unit unless specifically stated. Generic elements are supplied to suit the requested element size and electrical configuration, but final suitability must be checked by the licensed installer before installation.

1.8kW and 2.4kW elements supplied separately with a hot water unit include a 12-month supply-only parts warranty from the date of purchase, provided the element has been correctly installed by a licensed electrical contractor or licensed electrical licence holder and used under normal operating conditions.

This element warranty covers the replacement supply of the element only. It does not include labour, call-out fees, electrical work, plumbing work, fault finding, removal, reinstallation, testing, travel, downtime, damage caused by incorrect installation, or any other associated costs. Warranty may be declined where the element has been incorrectly installed, dry-fired, modified, damaged, connected to incorrect voltage or wiring, affected by power issues, used in unsuitable water conditions, or installed by an unlicensed person.

Proof of purchase, installer details, electrical licence details, photos, and/or return of the faulty element may be required before a warranty claim is approved.

**Tempering valve information:
Where a hot water system is capable of delivering water above 50°C, a compliant tempering valve must be installed to control the temperature delivered to personal hygiene fixtures such as showers, baths, basins, and bathroom outlets. This helps reduce the risk of scalding and assists with meeting plumbing compliance requirements.

A tempering valve blends hot and cold water to deliver a safer controlled outlet temperature to required fixtures. The hot water unit itself may store water at a higher temperature, but the water delivered to personal hygiene outlets must be controlled where required by plumbing regulations.

If your property already has a suitable, compliant tempering valve installed, your licensed plumber can assess whether it is appropriate for use with the new hot water system. Existing valves may not always be suitable due to age, condition, compliance requirements, valve type, location, or system compatibility.

If a compliant tempering valve is not already installed, or if the existing valve is unsuitable, one must be supplied and installed by a licensed plumber as part of the hot water installation.

Tempering valves are not automatically included with every supply-only hot water unit unless specifically selected, listed as included, or purchased as part of a suitable valve kit. If a tempering valve is required, please purchase the appropriate valve kit with your order or arrange for your licensed installer to supply and install the correct tempering valve on site.

It is the customer’s responsibility to ensure the installation is completed by appropriately licensed trades and that all required valves, fittings, electrical work, plumbing work, and compliance requirements are allowed for as part of the installation.
